Known Issues
The following high severity issues are reported in this release. For a list of the minor issues, see Knowledge Base article
SLN320772 PowerStore Release Notes – Minor issues at: https://www.dell.com/support/article/SLN320772
Table 2 Known Issues in this release
Issue ID Functional Area Description Workaround/Resolution
MDT-152854 Connectivity - Hosts Running an unmap operation might
cause a host I/O latency impact of
more than 15%. You can disable
auto-unmap for applications that have
this feature, or manually schedule an
unmap operation to reduce the impact
on hosts.
Disable auto-unmap for applications
that have this feature. Schedule
unmap operations manually to
reduce the impact on hosts.
MDT-154342 Connectivity - Hosts When you add a host, in rare cases,
you may not see any active sessions
or connected paths for the initiators
for up to 10 minutes on the Initiators
tab.
Do not try adding the host again.
Wait for up to 10 minutes for the
active sessions to appear.
MDT-148696 Connectivity - Hosts
When there is an active I/O operation
occurring between a host and
ColdspellX Fibre Channel port on the
appliance, and there is a considerable
amount of logout and login activity
initiated by the hosts, the port may
report a BUSY status back to the host

MDT-133408 Data Protection
When a volume group is created with
member volumes and is protected by
a protection policy that includes a
replication rule, the volume group
members may be delayed in being
replicated to the remote system until
the next RPO cycle. The default
replication rule RPO value in
PowerStore Manager is 1 hour, but it
can range from 5 minutes to 24 hours.
If the remote system connection is
healthy, the member volumes should
automatically be replicated to the
destination during the next RPO
cycle. To update the member
volumes on the destination before
the next RPO cycle, navigate to
Protection-> Replication, select the
volume group session and perform a
"Synchronize" operation.
MDT-148947 Data Protection From a protection perspective, a
snapshot of a volume group is a
single-point-in-time copy of the
volume group member volumes.
Membership changes to the volume
group prevent snapshot recovery
operations, such as restore or refresh,
unless the volume group is returned
to the same membership state at the
time the snapshot was created. It is
recommended that you do not delete
the volumes removed from a volume
group until all the snapshots of the
volume group either expire or are
removed manually.
If there are still volume group
snapshots, the delete request for the
volume returns the following error:
"The Volume <volume name> (id:
<unique id>) cannot be deleted until
all volume group snapshots taken
when this volume was a member of a
volume group expire or are manually
deleted." This error does not indicate
the name of the volume group that is
needed to delete the volume group
snapshots so the volume deletion can
succeed.
In PowerStore, first identify the
volume group name, if it is unknown,
by navigating to Snapshots table of
the removed member volume.
Volume group snapshots that have
been created by a protection policy
should have the volume group name
as part of the system-created
snapshot name for each member
volume. If there are only manual
snapshots, you can use REST API
to identify the volume group name.
The volume group snapshots can be
deleted by navigating to the
protection tab and viewing the
snapshots for the specific volume
group. Click Show/Hide Table
Columns and add the Volume
Members column. The column
appears and displays a number.
When you hover over that number,
the volumes within the VG snapshot
become visible. You can look for a
pattern by sorting this column. A
column with more members might
indicate that the VG snapshot has
the member that is preventing the
volume deletion operation, assuming
one or more members have been
removed and snapshots continued to
be created on the remaining VG
members.
MDT-146780 Data Protection When deleting a snapshot rule, the
snapshot rule may not appear to be
deleted, and the following error
appears: "The system encountered
unexpected backend errors. Please
contact support. (0xE0101001000C)".
Do not continue using the rule for
protection.
Delete the snapshot rule again. The
same error appears, but the rule will
be deleted.

Issue ID Functional Area Description Workaround/Resolution
MDT-117061 Hardware
When beginning cluster creation, the
hardware status is incorrectly
indicated as not configured for
clustering.
Wait a few minutes and try again.
MDT-137439 Import
If an import from a Unity or VNX2
system to PowerStore is cancelled by
the user or fails for some reason, it is
possible that subsequent attempts to
import the volume will also fail.
Remove the Unity or VNX2 as a
remote system and then add it
again. This action will clear the issue
and allow the import to proceed.
MDT-145764 Internal Migration During migration the temporary
volumes that are created during
migration are calculated into the vVol
capacity metrics. The temporary
volumes should not be included in the
calculation.
Wait for migration to complete to get
the correct calculation.
MDT-153885 Internal Migration If a volume is expanded while one of
the nodes is booting up, the size of
the volume might not be changed on
the node that is booting up. As a
result, I/O operations to the newly
expanded region of the volume fail.
Reboot the node that has the
problem or enter a ModifyVolume
command to increase the volume to
slightly larger size, which should
resolve the issue.
MDT-140927 Internal Migration
After a volume is migrated, there
maybe a dip in capacity and
performance metrics reporting for that
volume at the end of the migration
operation.
None
MDT-156905 Install or Upgrade After a software update, the NAS
servers may not fail back
automatically to the original node.
Manually fail back the NAS servers
from PowerStore Manager.
MDT-135505 Install or Upgrade
Drive firmware updates may not get
applied to a single or few drives within
the appliance. This may occur
because of a timing issue between
the two nodes in the appliance.
Download and install the drive
firmware again to ensure it gets
updated on the drives that were
missed in the previous attempt.
MDT-148659 Install or Upgrade If the peer node is inaccessible for too
long, the software upgrade can fail.
Retry the software upgrade.

MDT-155853 Monitoring
If there is a critical capacity based
forecasting alert, a migration
recommendation repair flow can be
used to migrate storage to another
appliance. It is possible that after
migration completes, the daily
forecast used to trigger the alert will
not be updated on the source
appliance and the alert will not be
cleared until the next daily forecast.
After the forecast is triggered again,
the capacity based forecast on the
source and destination appliance may
be inaccurate as a significant amount
of storage is migrated.
None
MDT-134036 Monitoring
When there is a contention of
resources, the performance policy
associated with the volume gets
applied. In the current release, you
may not notice much difference
between the High and Medium
performance policies. For volumes
with Low performance policy, expect
to see a noticeable difference in the
amount of I/O operations serviced as
compared to volumes with High or
Medium performance policies.
None
MDT-146346 Notifications and
Alerts
Some hardware alert states may
persist for a short time after the health
of the object has been restored. The
alert states eventually resolve with the
correct state.
None
MDT-153335 PowerStore CLI The PowerStore CLI does not show
all the required information for metrics
when a roll-up result is returned for
long interval values.
It is recommended that you use the
REST interface to query metrics.
You can also use any REST client
(cURL, Insomnia, Postman, etc.) or
web browser.
MDT-118394 PowerStore
Manager(GUI)
Uploading an upgrade package that is
larger than 4 GB with Microsoft Edge
or Internet Explorer fails.
Try again with a different browser.
MDT-86305 PowerStore

When you power down a node in
PowerStore Manager, the screen
does not automatically refresh the
state to indicate that the node is
getting powered off.
On the Hardware tab, click the
Refresh icon (appears on the top
right corner of the tab, next to the
base enclosure image) or refresh the

There are situations when the system
is Out of Space where the UI is
unable to update its statistics. This
situation will be evident by a red
banner on the top of the screen. You
may see objects in the UI that are
incorrectly displayed as "0

While performing a Refresh Using
Related Volume or Volume Group
operation, you might receive an
exception error when you select
Choose One from the drop-down
before you click Refresh. If this
occurs, you must restart PowerStore
Manager.
When refreshing a resource, do not
select the "Choose One" entry in the
Refresh from Volume/Volume Group
drop-down.
MDT-130894 PowerStore REST
API
Two invalid resource_types, FEPort
and Initiator, may be returned by the
event and alert APIs.
Events or alerts with resource_type
FEPort or Initiator should ignore the
resource_type values.
External OpenAPI clients must
disable validation for the event and
alert APIs with resource_types of
FEPort or Initiator.
MDT-153026 Security When a drive is inserted into an
appliance, it will take time for D@RE
to unlock it. Most drives take a few
minutes. However, it takes more time
for a ColdStream drive to unlock. The
time is proportional to the size of the
ColdStream drive, for example, 7
minutes for 375 G, 15 minutes for 750
G, and 27 minutes for 1.5T. If you pull
a drive out before it is unlocked, the
drive will appear as disconnected.
However, the drive will not be
automatically removed from the
appliance.
If you intend to use the drive, re-
insert the drive and let the DARE
unlock complete. If you intend to
stop using the drive, re-insert the
drive, wait for enough time (time to
unlock + about 1 minute for other
overhead), and then remove the
drive. The drive will then become
disconnected and automatically
removed from the system.
MDT-121966 Storage - File
The File system deleted alert is
displayed as an active alert in
PowerStore T even after the file
system has been successfully
deleted.
Review the alert details, to confirm
the alert is for a file system that has
been deleted. Once confirmed,
ignore or acknowledge the pending
alert.

MDT-156507 Virtualization
In high scale VMware vSphere
environments, where the ESXi hosts
and vCenter server are highly loaded
(for example, simultaneous powering
on a large number of VMs), heartbeat
messages sent by the ESXi hosts to
the vCenter server may not be
delivered in time. When the heartbeat
is not received in the 60-second
timeout interval, the host is
considered as not responding, and
the host is marked as disconnected.
This may result in the vSphere High
Availability (HA) to trigger VM
migrations to other hosts in the
cluster.
In vCenter server, increase the
heartbeat timeout interval to 120
seconds. See VMware Knowledge
Base article 1005757. In case some
VMs appear as invalid or orphaned
as a result of the ESXi host
disconnect, see the VMware
Knowledge Base article 1003742 for
instructions on recovering the VMs.
MDT-146763 Virtualization During a vMotion process, some
vVols are deleted. If the VASA
provider becomes unavailable during
a storage vMotion operation, the

16 Dell EMC PowerStore Release Notes
Limitations
The following limitations exist in this release.
PowerStore T and PowerStore X model limitations
The following limitations exist in PowerStore T and PowerStore X deployment models.
Functional Area Description
Importing external storage
to PowerStore
A maximum of 16 import sessions is supported in the Ready-For-Cutover state
during an import. In some cases, when several dozen import operations are run
back-to-back, intermittent failures of alternate import sessions may occur. If this
occurs, do the following:
1. Remove the remote system and then add it again.
2. Run fewer set of imports (16 or less) at a time. It is recommended to start all
these import sessions with automatic cutover turned off.
3. Once all imports have reached the Ready-For-Cutover state, do a manual
cutover.
4. After one set of imports is completed, run the next set of imports after a
delay of 10 minutes. This delay allows enough time for the system to
cleanup any connections to the source system.
PowerStore Management
access
There are some management functions which might be not available through the
appliance IP address. This is a known issue and we recommend using only the
cluster management IP address for managing the cluster.
PowerStore scalability
limits
The PowerStore Simple Support Matrix lists the scalability limitations in PowerStore
models. The PowerStore Simple Support Matrix is available from the Dell E-Lab
Navigator at: https://elabnavigator.emc.com/eln/elnhome
SCSI Persistent
Reservations Support
SCSI-2 clusters are not supported. Only the following SCSI-3 persistent reservation
(PR) clusters are supported:
• SCSI-3 PR is supported for single appliance PowerStore clusters, both for
PowerStore T model and PowerStore X model appliance types.
• In a PowerStore T model cluster with more than one appliance, SCSI-3 PR
is supported. However, internal migration of vVols between appliances in a
cluster is only supported for vVols without SCSI-3 PR when you are running
VMware vSphere 6.7 P02 or later. Support for internal migration of vVols
with SCSI-3 PR may be available in a future VMware vSphere release.
Note: In this release, a PowerStore X model cluster can contain only one appliance.
